Answer:
These stars are mistakenly referred to as G-type stars. Our Sun is a G-type star, but it is in fact white. G-type stars convert hydrogen into helium and usually evolve into red giants when their hydrogen fuel is exhausted. Some examples are: Alpha Centauri A, Tau Ceti.
Orange Dwarfs
These stars have a prevalence of around 10%, with a spectral type K. They have temperatures between 3.700 K to 5.200 K, with luminosities around 0.08 to 0.6 that of the Sun. They have a mass of 0.45 to 0.8 that of our sun and last around 15 to 30 billion years.They usually reside in the arms of spiral galaxies and are characterized by the strong Helium-II absorption lines in their spectra. They have weaker hydrogen and neutral helium lines in their spectra than B-type stars.
Because of their mass and temperature, they have short life spans that end in a supernova explosion resulting in either black holes or neutron stars. Some examples of blue stars: Delta Circini, V560 Carinae, Theta1 Orionis C.
Yellow Dwarfs
Yellow dwarfs have a 10% prevalence, with a spectral type G. They have temperatures between 5.200 K to 7.500 K, with luminosities around 0.6 to 5.0 that of the Sun. They have a mass of around 0.8 to 1.4 that of the sun and last about 4 to 17 billion years.
